Hi,
the lens may be recognised correctly by exiv2, but to be of any use in
the Lens correction module, there must be an entry in the lensfun
database, too. (I assume the image info panel shows the lens name
correctly.)
The web page linked by you tells you some info about lens calibration
and how to make your own. I personally use hugin lens calibrator. If
you cannot find any suitable subject with lines (a modern building),
you can try to create a striped pattern on your LCD and photograph it.
(It may not be the best approach due to short focusing distance, but it
works quite well.)
regards,
Milan
